Surgical philosophy:
Repair the trachea and the left pulmonary artery in the least traumatic way. Follow the LPA closely.
Innominate Suspension: for Innominate Suspension: for patients with innominate artery patients with innominate artery

Surgical Options:
Anterior tacking of the innominate artery to the sternum, or detachment and reimplantation of innominate artery
